The Osprey Stratos and Sirrus backpacks are day packs designed for day hikes or overnights in the backcountry. Combining comfort, ventilation, and organizational features, the Stratos and Sirrus packs deliver lightweight, technical performance
Built for long day hikes and overnights in the backcountry, the lidded Osprey Sirrus 36 Women’s pack combines carrying comfort, ventilation and organizational features to deliver lightweight, technical performance.
Committed to providing all outdoor enthusiasts with optimal performance, Osprey equips its women's packs with gender-specific design features. Harnesses are cut wider through the collarbone area and have an ergonomic taper in the chest area. Offering a women's specific cant and a narrower cut, the hipbelts found on Osprey's women's packs also cater to female users.
Employing Osprey's Airspeed Suspension, a 3D tensioned mesh backpanel provides flexible support and breathability to combat heat build-up between your back and the pack body. Both the hipbelt and harness straps are padded with die-cut foam and covered in mesh to enhance comfort and optimize fit. A webbing adjustable sternum strap further optimizes fit and includes a whistle buckle for safety. Upper side compression straps work in tandem with the InsideOut compression built on to the woven-mesh side pockets to allow you to cinch down the Sirrus 36 Women’s pack and keep contents stabilized.
The storage capacity of the XSmall/Small Sirrus 36 Women’s pack is 2075 cubic inches and the capacity of the Small/Medium is 2197 cubic inches. In addition to its traditional top access point, the main packbag can be reached through a front panel entry. A large front zippered pocket, two side stretch pockets and dual pockets in the lid of the Sirrus 36 Women’s pack offer additional organizational options. The pack also has a zippered lower sleeping bag compartment and zippered pockets on the hipbelt to keep small gear and trail essentials close at hand.
Other features found on the Sirrus 36 Women’s pack include a single Stow-on-the-Go trekking pole attachment on the shoulder strap, removable sleeping pad straps, a single ice tool attachment with a stowable bungee tie-off and an integrated rain cover. A lined internal sleeve and drinking tube pass-throughs make the pack compatible with hydration systems (sold separately).
The Osprey Sirrus 36 Women’s pack is available in your choice of colors and XSmall/Small (fits torso lengths ranging from 15"-18") and Small/Medium (17"-20") size options.

- If in doubt order the size up
Likes: 1. Comfy padding, especially "airspeed" trampoline mesh
2. Included, integrated raincover
3. Can access from both top and front, making it easier to get items at the bottom of the pack.
4. Hip belt pockets are a bit roomier than those on the Osprey Exos
Dislikes: 1. Fit seems to run small. My wife is 5'6" and ~130 lb. Using method on Osprey website we measured her torso as 17 inches. This is supposedly the bottom end for the S/M (17-20") and upper end of X/S (15-18"). We initially got the X/S and it was too small. S/M seems right and I suspect it would even fit someone who measured 16 inches in the torso.
2. The top "brain" ins't removable like it is on the Exos.
Likes: Bought this for my wife. She really loves the color. Likes that it has lots of pockets and really light.
Dislikes: The cinch tie on the main compartment is hard to open and close. It will probably get easier with use.
